HydroSprint — The Hydration Mistake Costing Sprinters Their Last 20 Meters

HydroSprint · Creatine + Electrolytes

The Hydration Mistake Quietly Costing High School Sprinters Their Last 20 Meters

Why more and more track parents are swapping sugary sports drinks and random pre-workouts for one simple, athlete-built scoop — creatine + electrolytes, nothing to hide.

HydroSprint creatine hydration powder by RMS Nutrition

Your athlete trains hard. So why do they fade?

Your athlete trains hard. But by the back half of the race — or the third event of a long meet day — they fade. Cramps. Heavy legs. A PR that slips away in the final meters.

Most of the time it's not effort. It's fuel and fluid. Teen athletes routinely under-hydrate and under-fuel, and the typical fixes make it worse: sugar-loaded sports drinks, or harsh adult pre-workouts loaded with stimulants that don't belong in a 15-year-old's body.

From the founder

I built the thing I'd give my younger self

Hi, I'm Finn. I'm a track athlete, and I built RMS because I got tired of two bad options: kiddie sugar water or jacked-up adult pre-workouts. I wanted something I'd actually give my younger self — and that a parent could look at the label and feel good about.

HydroSprint is the first thing I made: the two things that actually move the needle on a meet day, and nothing I'd have to explain away.

Two things, done right

HydroSprint is built on two things, done right:

  • Creatine monohydrate (5g) — the most-studied supplement in sport, to support strength, power, and repeat-effort output.*
  • Electrolytes — sodium, potassium, magnesium to support hydration through heat and long meet days.*

One scoop. No stimulants. No 30-ingredient mystery blend.

Parent-defensible by design

  • Full label, full doses — nothing hidden in a "proprietary blend."
  • Third-party tested. No banned substances. No fillers, no artificial dyes.
  • Made for athletes 13+ with a clean, structure/function formula.
